Great! What was your 60ft?

Edit: 60ft was 2.094. ECU tune + 100hp NOS + DRs = most probably very low 12sec.

 

Yes, my time slip was attached as a pic at the bottom of my post.

+125 NOS shot would = high 11's. If I added NOS, and traction, it is just a matter of jetting the NOS to get into the 11s if I wanted. If +100 doesn't do it, then 125 would, if that didn't, 150 would. NOS is easy like that.

I think I'm going to just try the ECU tune and some other small tweaks, get a run of 12.9x, then call the car done for now.

I may save the NOS for another project.

 

great results!!

did you ever run a 1/4 with the car stock?

Yes, in the above post I listed my baseline runs, best of 13.839 @ 101.43, but this is with a tune (approx +18 RWHP) which was removed since the basline 1/4 mile.

So, even with the approx 18 RWHP loss of the tune, my time improved .606 seconds and an increase of 3.9 mph.

I'm attributing most of the gain to the fact that more power comes on much sooner, so at every point down the track, I am moving a little faster. This is the difference between a dyno sheet and a real world drive.
